Kepala penis adalah tutup [[korpus spongiosum]] yang terbentuk di ujung tonjolan [[korpus kavernosum penis|korpus kavernosum]], meluas di sisi [[dorsal]] daripada [[ventral]]. Di pucuk kepala, terdapat [[lubang uretra eksternal (laki-laki)|lubang uretra eksternal]] yang berbentuk celah vertikal. Lingkar bawah kepala penis disebut [[korona glandis]] yang menjorok membentuk cekungan ''[[sulkus (morfologi)|sulkus]] korona'', menutupi leher penis. Bentuk proporsional kepala penis berbeda-beda, ada yang ukuran lingkarnya lebih besar daripada [[batang penis]] sehingga penis tampak menyerupai jamur, ada pula yang lebih kecil sehingga menyerupai roket[[torpedo]].

[[Kulup]] yang menutupi kepala penis berfungsi menjaga [[mukosa]] dalam keadaan lembap.<ref name="prakash">{{cite journal | last = Prakash | first = Satya | coauthors = Raghuram Rao, K.
